Definitions

  • the invention relates to a snap-in antenna, in particular for motor vehicles, which has a grommet made of elastomeric material, which is provided in its lower region with a circumferential locking groove for receiving a peripheral edge of an opening of a surface supporting the antenna, and in which a connector ⁇ antenna element is receivable.
  • Such a plug-in antenna is known from DE-4037712 C2 and from DE-4005 029 C2.
  • DE 4037 712 C2 also discloses a capacitive ground coupling of the antenna.
  • the disadvantage of this is that the assembly process of the antenna in a body hole in a body panel of a motor vehicle cannot be carried out by a single mechanic from the interior of this motor vehicle. It is therefore an object of the invention to further develop a plug-in antenna of the type mentioned at the outset in such a way that assembly is made easier.
  • the spout has an axially directed, annular recess in its lower end face, into which a locking ring which can be locked at this end can be inserted from the lower end face of the spout.
  • the measures according to the invention advantageously achieve that the assembly of the antenna according to the invention that can be connected can now be carried out without the mechanic being forced to use the support of a second person or during the assembly process Leaving the interior of the body of the motor vehicle to be equipped with the antenna according to the invention.
  • an advantageous further development of the invention provides that the locking ring can be locked on the grommet by a metallic earth ring, which at the same time advantageously capacitively couples the antenna element of the antenna according to the invention to ground.
  • This capacitive ground connection of the antenna to the body panel has the advantage that a good ground connection can be established in a particularly simple manner without damaging the body panel or a paint layer covering it.
  • a further advantageous development of the invention provides that a shielding of a high-frequency cable connecting the antenna element of the antenna according to the invention to a corresponding transmitting or receiving device can be fastened in the antenna element by means of a wedge made of metal or plastic. This procedure advantageously ensures that the HF cable can be attached in a particularly simple manner without soldering or crimping and with simultaneous strain relief.
  • a further advantageous development of the invention provides that an insulation body surrounding the antenna element and insertable into the grommet of the antenna according to the invention with coil tracks running on its outer surface, which at their ends merge into bores penetrating radially into the interior of this insulation body. is provided. This measure according to the invention advantageously enables the production of a blocking circuit with simultaneous coil attachment to the insulation body without being forced to solder or crimp the wire forming the coil to the antenna element.
  • FIG. 1 shows a partially sectioned view of an exemplary embodiment
  • FIG. 2 shows the assembly process of the exemplary embodiment in a body bore in a body panel
  • Figure 3 shows a cross section through the embodiment in the inserted
  • FIG. 4 shows a top view of the exemplary embodiment from the direction IV of FIG. 3, the bottom part of the exemplary embodiment being shown transparently
  • FIG. 5 shows a schematic sectional illustration of an antenna element of the exemplary embodiment
  • Figure 6 is a schematic sectional view of the upper part of the antenna element.
  • FIGS. 1 to 6 of an insertable antenna which is particularly suitable as a combination antenna for the D or E mobile radio network, is in principle divided into a spout 1 made of elastomeric material, which fits into a corresponding bore 2 'of a Body panel 2 can be used.
  • An antenna element 20, which will be described in more detail below, can be received in an interior 1 'of the hollow-conical nozzle 1.
  • the grommet 1 also has a radially directed latching groove 3 in its lower area, which is also known per se and in which the circumferential edge of the bore 2 'of the body panel 2 can be received in the inserted state of the insertable antenna described .
  • the grommet has a radially extending pre-notch 4, which, seen in the insertion direction X of the antenna, lies in front of the detent groove 3 which is designed as a circumferential groove.
  • This preliminary groove 4 advantageously allows the grommet 1 to be provisionally locked in the body bore 2 ′′ of the body panel 2 in a first assembly step of the assembly process, in order then - as shown in FIG. 2 - by means of an appropriate auxiliary tool H (see FIG. 2) or possibly - but this is not preferred - by a corresponding pull from the outside from its pre-locking position shown in FIG Figure 2 shown final To press the locking position in which the peripheral edge of the body bore 2 'is received in the locking groove 3.
  • the spout 1 is moved against the resistance of the circumferential flank 5 of the spout 1 arranged between the pre-groove 4 and the detent groove 3, which - like the entire spout - consists of elastic material.
  • the auxiliary tool H is immersed in an axially aligned annular slot 11 provided on the lower end face 10.
  • This ring slot 11 advantageously serves not only to insert the spout 1. Rather, it also causes an increase in the elasticity of the spout in this area as a result of the reduction in the spout material to be deformed thereby.
  • the ring slot 11 preferably also has a cavity 12 in the area of the locking groove 3, which is stretched when the auxiliary tool H is pressed into the ring slot 11 and also further reduces the wall thickness of the spout 1 in this area, which means that advantageously, the assembly process of the antenna described is further facilitated due to the even easier elastic deformability of the grommet 1.
  • a radial and axial seal of the spout 1 in the body bore 2 'of the body panel 2 now takes place by inserting a locking ring 13 matched to the ring slot 11 and possibly the cavity 12 from the end face 10 of the spout 1 and with the aid a mass ring 14 is locked so that the grommet 1 can no longer be pressed from the outside into the bore 2 'of the body panel 2.
  • the locking ring 13 is locked in the ring slot 11 in an advantageous manner by a part 14a of the earth ring 14 projecting into the ring slot 11. This part 14a engages - as can best be seen in FIG. 3 - a circumferential one arranged on the external locking ring 13 Shoulder 13 'and locked in such a way
  • the earth ring 14 serves not only for mechanically fastening the antenna in the body bore 2 'of the body panel 2. Rather, the earth ring 14, which is preferably made of stainless steel, achieves a capacitive coupling of the antenna to ground.
  • a dielectric is arranged between the electrically conductive body sheet 3 and at least part of the ring surface 14 ′ of the mass ring 14, which dielectric is preferably used as a dielectric adhesive film, as a coating or as a varnish, etc. on the body sheet 2 and / or the ring surface 14 'of the mass ring 14 is executed.
  • the earth ring 14 has fan-like spring segments 15a-15h in an annular arrangement, which are also preferably made of stainless steel.
  • FIGS. 5 and 6 now show details of the design of the antenna element 20.
  • the fixation of the described antenna which can best be seen in FIG. 5, is advantageous.
  • the high-frequency cable 30 connects this with a corresponding transceiver.
  • a shield 31 of the HF cable 30 is made of metal or Plastic wedge 32 is pressed against a mass part 21 of the antenna element 20.
  • Such a procedure not only has the advantage that a safe ground contact and - in the case of a metallic part - almost no change in impedance occurs at this point. Rather, the construction described also provides a strain relief for the HF cable 30.
  • Another advantage is that the shield 31 of the HF cable 30 can be connected to the ground part 21 of the antenna element 20 in a particularly simple manner and without crimping.
  • FIG. 6 shows a particularly simple way of producing and installing a blocking circuit on the antenna element 20 of the antenna described.
  • a groove 25 Arranged on an insulating body 23 surrounding the upper part 20a of the antenna element 20 is a groove 25 which serves as a coil path and extends in a helical shape.
  • the helical groove 25 goes to hers both ends in a radially extending bore 26, 26 ', which extends from the outside of the insulation body 23 to the interior 23' receiving the antenna element 20.
  • a wire 27 forming the coil of the blocking circuit is inserted through the upper bore 26 into the interior 23 'of the insulating body 23 to such an extent that by slightly inserting an upper radiator 20a Antenna element 20 in the interior 23 'of the insulating body 23 achieves a clamping of the wire 27 between the outer surface 20' of the antenna element 20 and the inner surface 23a of the insulating body 23 and thus reliable contact between the wire 27 and the antenna element 20 will be produced.
  • the wire 27 is wound along the helical groove 25 forming the coil path and then cut to length to pass through the groove located at the lower end of the coil path. to be inserted radially into the interior 23 'of the insulation body 23 forming the coil core 23 and to be pressed in by inserting a further radiator element 20b of the antenna element 20.
  • the antenna described is not only distinguished by the fact that it can be manufactured particularly easily. Rather, the structure described further enables the antenna to be installed by a single person from the interior of a vehicle body, without the aid of an assistant.
